Module Description

library to compute statistics


Uses


Interfaces

public interface GetMeanVector

  • private function GetMeanFloat(vector, nodata) result(mean)

    compute mean of a vector of real numbers. If nodata is passed numbers are filetered before computing mean

    Arguments

    Type IntentOptional Attributes Name
    real(kind=float), intent(in) :: vector(:)
    real(kind=float), intent(in), optional :: nodata

    Return Value real(kind=float)


Functions

public function LinearRegressionSlope(x, y, nodata, r2) result(lrs)

compute slope of linear regression between vector x and y

Arguments

Type IntentOptional Attributes Name
real(kind=float), intent(in) :: x(:)
real(kind=float), intent(in) :: y(:)
real(kind=float), intent(in), optional :: nodata
real(kind=float), intent(out), optional :: r2

Return Value real(kind=float)
